GLP-1 RAs Show Promise in Reducing Liver Disease Progression in Patients with MASLD and Type 2 Diabetes
A groundbreaking study has revealed that glucagon-like peptide-1 receptor agonists (GLP-1 RAs) may offer superior long-term liver outcomes compared to sodium-glucose cotransporter-2 inhibitors (SGLT2is) in patients with metabolic dysfunction-associated steatotic liver disease (MASLD) and type 2 diabetes (T2D). The findings, derived from a retrospective cohort study of over 150,000 patients, highlight a 16% relative risk reduction in major adverse liver outcomes (MALOs) among GLP-1 RA users, primarily driven by fewer decompensated cirrhosis events [[1]].
MASLD, the moast common chronic liver disease globally, affects more than 30% of the population. Despite its prevalence, treatment options remain limited, with resmetirom (Rezdiffra) being the only FDA-approved pharmacologic therapy [[2]]. The condition is particularly prevalent among individuals with T2D and metabolic syndrome, emphasizing the critical role of insulin resistance in disease progression. This has spurred interest in GLP-1 RAs and SGLT2is as potential therapeutic candidates [[3]].
To explore this further, researchers analyzed data from the TriNetX Research Network, focusing on adult patients aged 18 and older with T2D and MASLD who were prescribed either a GLP-1 RA or an SGLT2i between january 1, 2010, and June 1, 2023. The study excluded patients who had previously used medications from the opposing group within six months before or after the index prescription. Using propensity score matching (PSM), researchers balanced the groups based on 51 variables, including demographics, comorbidities, medications, and laboratory results [[1]].
The analysis included 28,912 new GLP-1 RA users and 17,707 new SGLT2i users.After PSM, 15,176 individuals remained in each group for outcome assessments. The results were striking: the GLP-1 RA group demonstrated a substantially lower risk of total decompensated events (aHR, 0.83; 95% CI, 0.71 to 0.96; P = .013) and all-cause mortality (aHR, 0.84; 95% CI, 0.75 to 0.94; P = .003) compared to the SGLT2i group.However,no meaningful differences were observed for hepatocellular carcinoma (HCC) (aHR,0.94; 95% CI, 0.63 to 1.42; P = .78) or liver transplantation (aHR, 1.21; 95% CI) [[1]].

GLP-1 Receptor Agonists Show Promise in Reducing Liver Complications for Patients with MASLD and Type 2 Diabetes
A recent study published in Alimentary Pharmacology & Therapeutics has revealed that glucagon-like peptide-1 receptor agonists (GLP-1 RAs) are associated with a lower risk of major adverse liver outcomes (MALOs) compared to sodium-glucose cotransporter-2 inhibitors (SGLT2i) in patients with metabolic dysfunction-associated steatotic liver disease (MASLD) and type 2 diabetes (T2D). The findings highlight the potential of GLP-1 RAs in reducing decompensated liver events, offering new hope for this high-risk patient population.
The study, led by Kuo et al., conducted a head-to-head comparison of GLP-1 ras and SGLT2i, two widely used classes of medications for managing T2D.Researchers found that GLP-1 ras were linked to a significant reduction in MALOs, particularly due to fewer instances of liver decompensation. “Our study demonstrates that GLP-1 RA treatment is associated with a lower risk of MALOs compared to SGLT2i, primarily due to a reduction in decompensated liver events, through a direct head-to-head comparison in patients with MASLD and T2D,” the investigators concluded.
Key Findings and Limitations
The study’s results are promising, but the authors acknowledged several limitations. These include the potential underrepresentation of mild cases, misclassification due to diagnostic codes, and the inability to fully eliminate residual confounding. Additionally, the study faced challenges in accurately assessing baseline fibrosis severity, which could impact the interpretation of outcomes.
Despite these limitations, the findings align with growing evidence supporting the use of GLP-1 RAs in managing liver-related complications in patients with MASLD and T2D. The American Association for the Study of Liver Diseases (AASLD) has recently updated its nomenclature to reflect the evolving understanding of liver diseases,emphasizing the importance of metabolic factors in conditions like MASLD.
Comparing GLP-1 RAs and SGLT2i
To better understand the study’s implications, here’s a summary of the key differences between GLP-1 RAs and SGLT2i in the context of MASLD and T2D:
| Aspect | GLP-1 RAs | SGLT2i |
|————————–|—————————————-|————————————-|
| primary Mechanism | Enhances insulin secretion, reduces appetite | Promotes glucose excretion via urine |
| Liver Outcomes | Lower risk of MALOs, fewer decompensated liver events | Higher risk of MALOs compared to GLP-1 RAs |
| Patient Population | MASLD and T2D | MASLD and T2D |
| Study Findings | Associated with reduced liver complications | Less effective in reducing liver events |
The Broader Context of MASLD Treatment
The study’s findings come at a pivotal time in the field of liver disease management. Earlier this year, the FDA approved resmetirom (Rezdiffra), the first medication specifically indicated for noncirrhotic NASH, a condition closely related to MASLD. this approval marked a significant milestone in the treatment of metabolic liver diseases, further underscoring the need for effective therapies like GLP-1 RAs.
What This Means for patients and Clinicians
For patients with MASLD and T2D, the study offers a compelling case for considering GLP-1 RAs as part of their treatment regimen. Clinicians should weigh the benefits of these medications against other options, particularly in patients at higher risk of liver complications.
